摘要： Provided is a high-sensitivity MEMS-type z-axis vibration sensor, which may sense z-axis vibration by differentially shifting an electric capacitance between a doped upper silicon layer and an upper electrode from positive to negative or vice versa when center mass of a doped polysilicon layer is moved due to z-axis vibration. Particularly, since a part of the doped upper silicon layer is additionally connected to the center mass of the doped polysilicon layer, and thus an error made by the center mass of the doped polysilicon layer is minimized, it may sensitively respond to weak vibration of low frequency such as seismic waves. Accordingly, since the high-sensitivity MEMS-type z-axis vibration sensor sensitively responds to a small amount of vibration in a low frequency band, it can be applied to a seismograph sensing seismic waves of low frequency which have a very small amount of vibration and a low vibration speed. Moreover, since the high-sensitivity MEMS-type z-axis vibration sensor has a higher vibration sensibility than MEMS-type z-axis vibration sensor of the same size, it can be useful in electronic devices which are gradually decreasing in size.
